A politician claims that she will receive 66% of the vote in an upcoming election. The results of a properly designed random sample of 145 voters showed that 80 of those sampled will vote for her. Is it likely that her assertion is correct at the 0.01 level of significance?

Question

Find the p-value. (Give your answer correct to four decimal places.)

Answer 1

p-value is the probability of obtaining the observed sample result, in this case the "properly designed random sample."

p(vote)= 80/145
= .55
= 55%

.55 DOES NOT equal to 66% or .66
